Ta allwho/witmag concern:

Be itknown that l, JQHNYT. S'roNEr, a citizen of the United States, residing at Cleveland in thecounty off Guyahoga. and Stateofj hi0, have invented a certain new and usefulj Improvement in hiolding Ma chines, of which the following is a. full,

. clear, and'exact description.

s nv ntion relat s. '11 general o m lding machines, andfmore particularly. to apparatus for supporting a mololing table jin such positionthat it jmay. be, adjacent a jarring table or; platformwvhich is raised and lowered by any means, andmay also be removed from suchplatform atwill.

The invention further includes mechanism whereby the molding tablemay be raised and lowered, and mechanism-whereby the molding table ma be, rolled Over.

7 Generally spea ring, the i invention comprises the elements and combinations thereof set forth in the accompanying claims.

Reference should be. had'to the; accompanying drawings forming a part of this specification, in which Figure 1 is a front elevation ofthe machinein section, l ig. 2 is. asideelevation with parts of the machine in section; Fig. 3isa topplan view of the machine with parts in section; Fig. 4'is an elevation with'parts in section, showing a detaihof the lockingmechanism. for the table.;Fig. 5 is an elevation withparts in section taken atlright angles to the showing in- Fig. 4; Fig. 6 is a'front elevation; Fig, 7 is a side elevation with portions in section ofa modified form ofmachineaFig. 8 is a side elevationofaportionof a still further modified formof machine 'a l ldfiFig. 9 is an elevationpartly in section, showing ad'etail of construction of the machine] shown in the table 1 to be continuously raised or low? ered within-certain limits, or permitting the table to be quickly moved up or down, or jarred. f

I have notshown'any mechanism for operating the table 1, inasmuchas this mecha- HISIIZL formsno, part ofmy invention, and as before stated, any desired form of such mechanism may be used. V

The device of my invention is. intendedto cooperate with sucha'table or platform, as

re resented at '1.

The whole apparatus is usually. contained within ,a p t such as represented .at' 2, for the apparatus is so bulkythat itwould otherwise be necessary for the workmento operate upon a. platform. It. has been found more convenient .to sink the apparatus below the level of the working floor and permit the men to worlixupon the floor. The pit'is coveredfby means of a 'platform 3, which will need no further description. At 4there is indicated a molding table which is adapted to support the flask which is generallyrepresentedat5. This table 4: has side arms 4 which are mountedupon trunnions 6. through journal blocks 7, which are mounted in a head piece generally represented at 8, *nd shown in Fig. 2. This head piece comprises sides 8"betwe'en which the. journal block 7 is mounted, and-the length of the side pieces 8 is such that the. journal block 7 may have a certain amount of vertical movement'relative to. the head 8. These arms-8? aresecured at their upper portions by means of a cross bolt 8.

The heads 3 are supported at the upper These 'trunnions extend end ofvertical supports 9,these supports 5 being mounted instandardslO. The standards are so formedas 'to provide a guide for, the. supports 9, insuring their moving ina vertical direction when it is desired to lift the molding table. I

. U pontrunnions 6 thereare flanged wheels 6 these wheels being secured to the trunnions thereby to turn as the wheels turn.

securedto the wheels 6'1 is one endof the flexible element'orcable 6", which flexible element "at its opposite end is secured to the standard 10. When tableeis raisedthe,

pulley or cable 6* wheels 6*will cause them toturnandso roll over the table 4. The reverse of the operation just' described takes place when table 1 is subsequently lowered.

There is sufficient loose play in the flexible element 6* so that the roll over molding table may move with the jarring platform. The standards 10 are mounted upon a platform 11, and the supports 9 may ex tend through suitable openings provided in the platform 11, and if ofnecessity the supports 9 are suliiciently long, depressions 1.2 may be provided in the floor of the pit, to accommodate the supports.

The supports 9 may be raised by various forms of mecnanism,-one of which forms 1s shown in Figs. 1 and 2, which will now be described.

The platform 11 carries two upright supports 13, which at their upper ends form journals that receive a transverse shaft 1ft. This shaft forms a pivot upon which 1s mounted a lever construction.

The forward end of this lever construction provides outwardly extending arms 15, the

arms preferably being formed of structural members which are suitably united to form a rigid and strong structure. Upon the ends of each of the arms are carried end pieces 16 which are forked as clearly shown in Fig. 2, the forked portion being substantially rectangular and forms a mounting for blocks 17, which blocks may freely slide in the rectangular forked portions of the members 16.

The blocks 17 are carried upon pins 18, which pins'are mounted upon collars 19, that are adjustably secured upon the supports 9. As will be apparent, these collars 19, by their adjustment may be caused to elevate the molding table to a greater or less extent when the arms 15 are rai lowered.

The arms 15 are secured to a sleeve 20 which is supported upon a shaft 14-. Extending rearwardly from the sleeve 20 are arms 21, which at their extreme ends are provided with journals that receive a shaft 22, this shaft being held by collars 22 carried upon the ends thereof and outside of the arms 21.

Upon the shaft 22, and upon that portion pieces which confine theiblock 23, so that the block may slide longitudlnally with respect to these sides. The sides 24 are secured to end pieces 2% which are 1n the 'form of sleeves, the sleeves being mounted j is united to a piston 28. The cylinder and piston are of proper construction to be worked by means of compressed air, or by steam, which finds an entrance and exit by the port 29.

The mechanism which has heretofore been described as mounted upon the platform 11, is preferably adapted to be shifted as a unit with respect to the table or platform 1. This may be accomplished in various ways,

'31. This piston rod extends within a cylinder 32, and cooperates with a piston there'- in, which piston may be operated in the cylinder by 'means of compressed air or steam, which operation, as will be clear, will cause the platform of the car to be moved forwardly or backwardly according to the direction in which the piston within the cylinder 32 is driven.

The operation ofthe device is as follows: The molding table 4. is adapted to receive a flask suchas indicated at 5, the molding table also having a pattern plate attached thereto which lies within the flask 5. Sand is poured into the flask 5 and the table 4 is allowed to rest upon the jarringplatform 1. With things thus arranged the jarring table is operated, and due to the manner in which the trunnions of the table 1 are mounted with respect to their supporting means, the table may have a limited amount of move mentwhich will be ani cfly'suflicient to jar with the platform 1. hen the arring is complete a board placed upon the top of the flask, and suitable means is employed to hold the board to the flask. The supports for the table are elevated, andthe table 4: is rolled over either by hand or by the mechanism described for this purpose.

When the table is rolled over the platform 1 is raised until it engages the lower end of the upturned flask. The flask is then released from the table 4, and the table 1 lowered, which draws the mold from the liiattern. lowered the molding table and its supports, together with the mechanism for operating the supports, is bodily moved with respect to the platform 1, and the mold resting thereon, so that the space above the mold is entirely free and unobstructed, and the mold can readily be removed from the platform 1 by means of a crane or any suitable apparatusfor the purpose.

In Figs. 6 and 7 I have shown a modified form of mechanism for mounting thetrunnion of the roll-over table, and the mechanism for directly raising and lowering these TV hen the 1 )latform 1 has been 1 ,BAWO
